ABSTRACT:
A modulator circuit provides pulses of electrical energy to an electrical load in response to a trigger signal. A normally nonconductive Mosfet is included in a series circuit path with the electrical load and a capacitor. A silicon controlled rectifier (SCR) is coupled to the gate electrode of the MOSFET. A trigger signal renders the SCR conductive to thereby render the MOSFET conductive which discharges the capacitor through the electrical load to provide a pulse of electrical energy having a rapid rise time to the electrical load. The electrical load can be a laser diode which emits a pulse of light for use in an optical ranging device in response to the pulse of electrical energy. The accuracy of the ranging device is proportional to the rise time of the pulse of light.
